Ok, my HP lappy running master.today still defaults to powersave, with
CONFIG_CPU_FREQ_DEFAULT_GOV_SCHEDUTIL=y, still disallows selecting
ondemand as before, and powersave still works. IOW for lappy, it was
business as usual, no change.

Desktop box did, it gained a working ondemand, while its previously
working powersave went broke. Box had schedutil forced upon it, but it
seems perfectly fine with that performance wise.
